Safety control device and control method for motor vehicle license plate production equipment

Abstract

The present invention provides a safety control device for motor vehicle number plate production equipment, which can prevent the problem of data leakage or tampering during the identification process of the number plate, and can prevent the number plate production site from using non-recorded number plate production equipment. Number plate production, so that the entire number plate production process is in a controllable state. At the same time, the invention also discloses a safety control method based on the safety control device. The safety control device includes a national secret algorithm security chip, and the national secret algorithm security chip performs USB communication with the main control PC and the identification camera unit of the number plate production equipment through the expansion interface of the USB-HUB chip, and communicates with the number plate production equipment through the RS232 serial port The electromechanical control device performs data communication, monitors the working voltage of the electromechanical control device of the number plate production equipment through the switching value detection module, and controls the electronic valve of the electromechanical control device of the number plate production equipment through the electronic valve driving switch module.

Description

technical field [0001] The invention relates to the technical field of motor vehicle number plate production, in particular to a safety control device and control method for number plate production equipment. Background technique [0002] The existing motor vehicle number plate production equipment includes equipment control PC, number plate production equipment electromechanical control device, number plate production application software running on the equipment control PC; the general production process of motor vehicle number plate production is: the operator logs in and runs The number plate production application software on the control PC of the number plate production equipment requests production from the number plate management information system through the public security network or private network; the number plate management information system responds to the request, generates the number plate queue information to be produced, and transmits it to the number pla...
